Early Childhood: Physical and Cognitive Development

Vocabulary flashcards reviewing physical, motor, cognitive, and language development during early childhood, based on Piaget's and Vygotsky's theories.

Early Childhood Body Growth

A physical development phase where the rate of growth continues to taper off from toddlerhood, resulting in a more streamlined body shape.

Brain Development (Ages $2$ and $6$)

The brain reaches approximately $70\%$ of adult weight by age $2$ and $90\%$ of adult weight by age $6$, demonstrating a general size-function correlation.

Recommended Motor Play for Preschoolers

At least $60$ minutes a day of adult-structured play, complemented by several hours of child-directed play, utilizing appropriate play spaces and equipment.

Car Seat Restraint Safety

Safety measures where $\frac{1}{4}$ of parents fail to use car seats, and between $40\%$ to $84\%$ use them incorrectly; under Illinois law, children must remain in a rear-facing seat until age $2$.

Tadpole Figures

A drawing milestone characteristic of $3$- to $4$-year-olds featuring basic, head-like figures with limbs directly attached.

Pencil Grip Milestones

Up to age $3$, children use varied pencil grips while scribbling; by age $5$, children typically achieve an adult pencil grip.

Piaget's Preoperational Stage

The cognitive development stage spanning ages $2$ to $7$, where sensorimotor activity generates internal images of experience that children label with words, preceding operational thought.

Operation (Piaget)

An internalized action that allows children to do mentally what before they had done only physically; characterized as reversible mental actions.

Egocentrism

A preschooler's limited ability or failure to distinguish others' symbolic viewpoints, understandings, and beliefs from their own, assuming their perceptions and thoughts are shared by everyone.

Animistic Thinking

Assigning inanimate objects lifelike or human-like qualities; considered a form of magical thinking that Piaget viewed as immature.

Egocentric Conversations

Dialogue reflecting Piaget's idea of externalization of thought rather than social communication, symbolizing current cognitive limitations.

Perceptual Salience (Centration)

The tendency of young children to center on the single most obvious feature of an object or situation while ignoring other relevant factors, causing them to be fooled by appearance.

Conservation

The cognitive understanding that changing the physical appearance of an object does not alter its basic physical properties such as quantity, mass, or volume.

Piaget's Class Inclusion Problem

A task (e.g., asking if there are more red flowers or flowers) where preoperational children fail to decenter from color groups and mistakenly choose the subcategory (red flowers).

Reversible Thinking

The capacity to mentally progress through a sequence of steps and mentally undo them to return to the initial starting point; this ability transitions a child into concrete operational thought.

Theory of Mind

The understanding that people possess unique thoughts, beliefs, and intentions that guide their behavior, and that different beliefs lead to different actions.

Metacognition

The cognitive process of thinking about thinking.

Fast-Mapping

The ability of young children to learn and connect a new word to an underlying concept after only a single exposure, often by contrasting it with known words.

Overregularization

The application of regular grammatical rules to words that are irregular exceptions, such as using 'goed' instead of 'went.'

Pragmatics

The practical, social side of language, involving conversational turn-taking, sustaining interactions, and asking for clarifications.

Private Speech

Self-directed speech that guides one's thought and behavior; viewed by Vygotsky as the foundation for all higher cognitive processes and the precursor to silent thinking.

Egocentric Speech

Piaget's term for self-directed speech, which he believed demonstrated cognitive immaturity and reflected a child's current thinking level rather than facilitating development.

Sociocultural Theory (Vygotsky)

A developmental theory positing that thinking is social in origin and develops from the 'outside-in' through cultural apprenticeship and environmental interaction.

Zone of Proximal Development (ZPD)

A range of tasks that are too difficult for a child to master alone but can be learned with the guidance and assistance of a more-skilled partner.

Scaffolding

Adjusting the level of structured support offered by a more-skilled person during a teaching session to fit the learner's current performance level within the ZPD.

Guided Participation

A shared endeavor between an expert and a novice involving active, co-participatory engagement in culturally meaningful activities like cooking, self-care, and routines.

Assisted Discovery

A Vygotskian educational approach where teachers guide learning, provide demonstrations, and tailor support directly to each child's zone of proximal development.

Discovery Learning

A Piagetian educational concept where teachers provide rich environments that promote spontaneous, independent interaction and exploration based on readiness to learn.

Child-Centered Programs

Preschool programs where learning is believed to come from within, emphasizing social skills, play, and intrinsic curiosity over standardized testing and rigid academic outcomes.

Teacher-Directed Programs

Early childhood programs where teachers deliver structured instruction with specific academic outcomes in mind, emphasizing routines, authority, and preparation for future testing.
